edge area is placed around the sides of the content box. The innermost area
is the Style.padding area which has a background and surrounds the
content. The content and padding area is surrounded by the Style.border,
which itself is surrounded by the transparent Style.margin. This box
represents the eges of padding, border, or margin depending on which
accessor was used to retrieve it.
